As far as I know, there is not a JDOM method or another automatic method to
do this.
The way I resolve this is by making a constructor for Customer that takes an
Element pointing to a customer tag, then reads the children of that tag.
Element e = parent.getChild( "customer" );
Customer c = new Customer( e );
If you want to separate the JDOM/XML parsing away from the design of the
Customer class (there are various reasons you may object to putting JDOM
code into the Customer class, espically if you did not write the Customer
class), you could use a sort of factory.
If your XML is pretty structured and you aren't sure what you are going to
get out of it you could use a generic factory that returned an object
implementing an interface, and the specific type is dependent on the tag
passed in. Or, if you do know what you are getting, then you could do
something like:
Element e = parent.getChild( "customer" );
Customer c = XMLObjectFactory.makeCustomer( e );
makeCustomer would presumably read out the fields and call a verbose form of
constructor for Customer to construct an appropriate new Customer object.
